WebThe Rose–Vinet equation of state is a set of equations used to describe the equation of state of solid objects. It is a modification of the Birch–Murnaghan equation of state. The initial paper discusses how the equation only depends on four inputs: the isothermal bulk modulus, the derivative of bulk modulus with respect to pressure ′, the volume , and the … WebPolynomial equations whose coeﬃcients are integers or rational numbers are called Diophantine equations, and the study of their integer or rational solutions is called arithmetic geometry.
